Almost all metals form polycrystals while amorphous single-crystal metals are created synthetically. What this means is that metal crystals are actually many crystals that bonded. This is what polycrystals are and how they are combined with metal crystals.

Explanation:
She should listen to him because she is a water nymph from Percy Jacksons father and she is very trustworthy. Spoiler Alert, He goes to Santa Monica and His father is correct and the Beach at Santa Monica helped him succeed in his quest.
Answer:
1. Co-variance= -1.2
2. correlation coefficient= -0.4404
3. There is weak negative relationship between x and y.
Explanation:
1.
Co-variance= Cov(x,y)= sum[(x-xbar)(y-ybar)]/n
xbar=sumx/n=32/5=6.4
ybar=sumy/n=35/5=7
x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
Cov(x,y)= sum[(x-xbar)(y-ybar)]/n=-6/5=-1.2
Cov(x,y)=-1.2
2.
correlation coefficient=r

x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
(x-xbar)² 0.36 2.56 1.96 11.56 6.76
(y-ybar)² 0 4 4 0 0

r=-0.4404
3. Since the value of correlation coefficient is negative and less than 0.5 , so, we can say that there is weak negative relationship between x and y.
Answer:
<em>c.cognitive dissonance. </em>
Explanation:
<em>In psychology, </em><em>the term cognitive dissonance is described as the discomfort experienced by an individual because of holding different conflicting values, ideas, and beliefs more or less at the same time. A person who is experiencing cognitive dissonance tends to hold conflicting attitude and thinking-pattern and due to which the person feels uneasy.
